The Roku HD is an excellent alternative to the Chromecast. Amazon has the older Roku HD (refurb) for $37.95 with free shipping. The Roku HD is great for TV’s without an HDMI port as it has composite video connectors (has HDMI as well). The Roku HD is capable of streaming Amazon Instant Video, Netflix, HBO GO, Hulu and more. Of course if you are looking for something a little bit more robust, check out the Amazon Fire TV.
